Water-based nano tungsten disulfide isothermal die-forging lubricant with high anti-friction and anti-wear properties and preparation method of lubricant

Abstract

The invention discloses a lubricant. Through usage of nano bentonite and acrylic ester, the suspension property of the lubricant is improved, caking, turbid and precipitating phenomena are avoided within 72 h, the adhesion property to metals is improved, pores are reduced, and workpieces are prevented from being damaged due to extrusion; through usage of nano carbon spheres, reaction of tungsten disulfide with the metals is reduced, and the lubrication persistence is improved; through matched usage of nano hydrotalcite, zinc acetate dehydrate, La2O3 nano-particles and ammonium dihydrogen phosphate, boundary lubrication films mainly comprising Fe2O3, La2O3 and the like can be formed on aluminium profile friction pair surfaces during friction, the lubrication films are firmly combined with the metals and show the excellent anti-friction and anti-wear properties, chemical components are stable, and the metals and dies are not corroded.

Description

technical field [0001] The invention relates to the technical field of forging lubricating fluid for aluminum profiles, in particular to a high-anti-wear and anti-friction water-based nano-tungsten disulfide isothermal die forging lubricant and a preparation method thereof. Background technique [0002] Isothermal die forging is a method of realizing die forging at a slower forming speed while keeping the mold and the workpiece at the same temperature. Since the workpiece is deformed at a lower strain rate at high temperature, the deformed material can be fully recrystallized, so that It overcomes the influence of work hardening, so it is very suitable for forming and processing parts with complex structure and high strength. In the process of die forging, friction will hinder the flow of metal, increase the forging load, consume deformation energy, cause uneven structure of the workpiece, dissatisfaction of the cavity filling, and reduce the service life of the die. Therefo...
